euporie's Issues

image rendering on alacritty

Is it a known limitation in Alacritty terminal that can't render the images well?

I don't know anything about sixel and not sure if is usable on Windows. I installed timg in my python env and it broke it.

euporie-console not working

See screenshot. Not able to type anything.

Dragging the scrollbar to scroll is extremely finnicky

When I use my mouse to left click-and-drag the scrollbar in Euporie Notebook, the scrolling is very irregular. Additionally, when I release the left mouse button, the scroll bar sometimes continues to be dragged with the vertical motion of my mouse; an additional click on the scrollbar seems to remove this effect.

The versions of software I am using, as well as a GIF that demonstrates my issue, are included below.

Cursor becomes invisible after exiting notebook

Very impressive repo!

This minor issue is annoying that I have to enter then exit Tmux to recover the cursor.

This behaviour has been confirmed in Kitty, iTem2 and Windows Terminal, so I believe it is not Terminal Emulator-related issue.

Nukes cells after navigating

Hey!

I am amazed at this tool. Very useful! I have unfortunately found an issue which renders it near-unusable for me.

I edit cells with an external editor, but sometimes cells "revert" to their previous content after saving and navigating away from the cell. For example, I add some code using my editor (Neovim), save the code and drop back into Euporie. Randomly, cells suddenly become empty if I navigate away from them, or run them.

Any idea why this might be? I could maybe contribute a solution if you could point me in the right direction.

Euporie does not work in Alacritty (without Tmux?)

Hello again!

I am having a really weird issue, where Euporie doesn't output anything if launched from Alacritty, but works fine in gnome-terminal. Also, works fine if run from Tmux within alacritty?

When i run Euporie from "vanilla" Alacritty, there's no output. If i press Ctrl-C, the output is:

Traceback (most recent call last):

Tmux is an OK workaround for me, just thought I'd let you know.

Stupid question: Installing from git

Dear developers,

I intended to clone directly from git and install it from there, but I could not find a setup.py. How does it work?

Best,

Feature Request: Change terminal cursor shape depending on mode

Howdy!

I'm really loving the direction euporie is headed. One small request would be to allow customization of the cursor depending on the editing mode. Many people who use modal text editors (e.g., Vim, but not trying to flame any wars) configure their editors to change the cursor shape depending on the mode. For instance, I use a block cursor for command mode and a vertical bar for insert mode (as well as an underline for replace mode, but the former is way more important).

This could be done easily by allowing the user to set a string that may contain escape sequences that is emitted during mode changes, akin to Readline's vi-ins-mode-string and vi-cmd-mode-string. This would also enable further creative uses.

If you'd be willing to provide some pointers to spots in the codebase, I'd be happy to attempt an implementation.

Thanks again for your awesome work!

Feature request: Some ideas for improving input cells

First off: absolutely stoked to see this project - comes so close to my ideal workflow that I got very excited brainstorming additional suggestions. Thanks a ton!

Right now, my jupyter TUI workflow is essentially using Neovim on a left kitty split and ptipython on the right side (i.e. ptpython using the ipython shell. This works surprisingly well for everything (and works across every language, too, just need a REPL). Here's some ideas coming from that.

There is a couple of niceties that ptpython does that would be absolutely fantastic to have in euporie

1) improved vim mode:

ptpython allows you to use vim on an individual input cell. right now to my understanding euporie only allows it on a notebook level, however this basically forces me to use e for every simple edit, which is kind of disturbing to the workflow since I have to do e -> <edit thing> -> :x -> ctrl-r.

Cooler would be if it would be solved like in the jupyterlab vim extension where single escape gets you to normal mode in a jupyter notebook level and shift escape or double escape gets you to vim mode on a notebook level. Another way to remove friction here is to make a write of the temp file executes the respective cell, so we could at least get rid of the last ctrl-r (by the time of write I'm pretty committed to executing it so the ctrl-r feels superfluous).

It would also be helpful to make sure that the tempfile has the right filetype (e..g use .py ending to make sure the editor filetype recognition works and you have LSP etc available)

2) function signatures and other advanced features (or even LSP support)?

3) autosuggestion

4) completion while typing

(3/4 look something like this in practice)

5) Variable viewer

Like the jupyterlab equivalent

Contribute to prompt-toolkit?

I see you have implemented something similar to ScrollablePane in ScrollingContainer (maybe more efficient, or with more features?). Could you tell a bit more about it? Do you think you could contribute upstream in prompt-toolkit?

Apologies for opening so many issues!

Just ran into an issue with completion. I can reproduce this error reliably when using tab-completion on this locally installed package (pip install -e .). As soon as I press the tab key, I get the following (from priv_lib.che is the private library, I pressed tab after the che)

ImportError in Python 3.8

Hi @joouha ,

Thank you for the awesome tool!

Using Python 3.8, euporie v2.1.1 returns the following error.

$ euporie notebook foo

Could you please replace functools.cache with functools.lru_cache(maxsize=None), same functionality supported in Python 3.8, as suggested at https://stackoverflow.com/a/66846753 ?

Gnome-terminal shortcuts

Do you know how to get cltr+enter and cltr+shift+enter to work in gnome-terminal?

seems I need to do something like this but not sure what I'm looking for
https://github.com/joouha/euporie#key-remapping

I confirmed that all three enter, cltr+enter and shift+cltr+enter return the same thing by running showkey -a and they all return ^M or the 0x0d which is the \r character

Add an item under the "Help" menu to show current shortcuts

This helps users get started with euporie more smoothly.

jupyter-client >= 6.2.0

Awesome project!
I see you require jupyter-client>=6.2.0, but the latest working version is 6.1.12 (6.1.13 and 6.2.0 were yanked).

Incorrect Description of Changing cell type

Changing Cell's Type has incorrect description .
It is explaining how to close notebook instead of how to change cell's type.
Corresponding file in repo.
Maybe we can add good first issue

[Q] Any ideas on how hard it is to display images in TUI emacs via the Kitty protocol?

I have been wondering about this for some time, but I had not seen anyone who knows enough elisp and Kitty to ask.

Remove shadow

Please, how can I remove the shadow?

Plots with matplotlib

Dear developers,

Somehow I experience this bug that the plot turns black once I move around to other cells. I saw that you were using matplotlib as well in your examples, did you have a certain configuration for your gui?

Best,

Refresh notebook

Would it be possible to implement (1) a menu entry that refresh the notebook (i.e. reload it from file) and (2) a feature that continuously monitor the notebook file for changes, and if there are changes, automatically reload it?

The use case is: I edit the notebook in plain vim with the percentage format, and then convert it back to notebook format with jupytext.

I know euporie has vim keybindings, but I have a whole ecosystem in vim which goes beyond keybindings (custom keybindings, plugins, etc.), so I would like to edit the notebook in plain vim, and update it with jupytext.

It would be great if euporie could refresh the notebook automatically.

AttributeError: 'NotebookApp' object has no attribute 'background_tasks'

This is such a cool app! Thank you for this! :)

I tried to run it in iterm2 using Python 3.11.0 on macOS Ventura (13.0.1) after running:

python -m pip install --user euporie
euporie-notebook

And it launches, but when I do CTRL+n to create a new notebook, it unfortunately gives an error:

I can't select the ? in that image, but I can select copy traceback, which doesn't do anything immediately, but if I hit CTRL+q, it prints the following traceback

How to enable image rendering in kitty terminal?

I open notebook in Kitty terminal but images are rendered by ascii character. How can I enable kitty image rendering feature?

Notebook object has no attribute inspect

When I try to use the --autoinspect swtich, whenever I try to type something I get the following errors.
I'm using the standard ipython kernel.

Images not displaying in console but do in notebook

Hi, thanks for sharing this incredible project. I've just started using the console and am having trouble getting images to display from matplotlib.

I'm using WezTerm and from running console with logging, the images are being rendered with chafa. In euporie notebook everything is working great. But in euporie console, the same commands yield only a blank space.

I've tried using a couple of other terminals and found that Kitty has the same issue while Gnome terminal or Gnome console works (with inferior rendering of course).

Let me know if there is any additional information I can provide for this.

Close the menu?

It may be me, but I think <Escape> should close an open menu?

Instead only <Tab> seems to do the job.

Is this intended?

StdinNotImplementedError: raw_input was called, but this frontend does not support input requests.

I just tried using %debug, however encountering the following

partial sixel rendering

While playing with your euporie browser example I saw that you do a low quality prerendering of graphics while they are not fully in viewport, and once they are fully in the viewport, switch to better quality with sixel.

This currently raises 3 issues:

low UX, as peeps first see a blurry preview like thingy
issues with overly big graphics not fitting into the viewport - no chance to get nice quality output here at all?
(blurry preview still has cell width issues, at least in the browser variant)

Thus I wonder if it would be feasible to do partial sixel rendering.

Now the main issue with sixels is - it is very expensive to convert the original image into sixel in the first place, as it needs quantization and dithering. So ideally one want to do that only once and cache the result.
On the other hand the advanced image algos needed for sixel conversion kinda make pre-slicing the original image into line parts and separately convert to sixel a no-go, as the created color palettes and dithering pattern are not stable (would lead to ugly stitching artefacts).

A possible solution to all those downsides would be a sixel-cropping library, eg.:

create full sixel repr of the original image
crop into that sixel as needed (pull pixel area WxH with needed colors)
print the cropped part

A more involved solution would be to write own sixel converter capable to freeze the color palette, and do the substitution on slices of the original image. This would need one initial quantization step creating a color substitution map with dithering marks. With that slices can be created pretty fast and memory efficient. (I suggested something similar here for the julia peeps, as they are keen to code such a thingy on their own).

So I wonder if you are interested in such an enhancement for sixel output. In general I'd lean more towards to the sixel-crop library idea, which should be straight forward to implement.

question: sample config file for different kernel

Hi, Can someone give me a config file example for euporie notebook for non-default kernel name and kernel connection file? I am using it on Windows and can't connect to an existing kernel in a python venv.

C:\Users\asharaf>jupyter kernelspec list
Available kernels:
  python3    C:\Users\asharaf\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone\share\jupyter\kernels\python3
  xpython    C:\Users\asharaf\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone\share\jupyter\kernels\xpython

How to hide cell output?

Sorry for the question here but I couldn't find a discussion section nor a IRC chat.

How can I hide the output of a cell?

non-default kernel issue on Windows

I've tried euporie on WSL (with Ubuntu) and it works. Now I need to use it on Windows because my python package (arcpy) is just running on Windows. I installed it via pipx on Windows but cannot configure it with a non-default kernel. Is it something you can help?

my existing kernels:

C:\Users\asharaf>jupyter kernelspec list
Available kernels:
  python3    C:\Users\asharaf\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone\share\jupyter\kernels\python3
  xpython    C:\Users\asharaf\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone\share\jupyter\kernels\xpython

euporie configuration file:

PS C:\Users\asharaf\AppData\Local\euporie> cat .\config.json
{
  "color_scheme": "dark",
  "syntax_theme": "native",
  "notebook": {
    "expand": false,
    "always_show_tab_bar": true,
    "show_cell_borders": false,
    "kernel_connection_file": "C:\Users\asharaf\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone\share\jupyter\kernels\python3\kernel.json",
    "kernel_name": "python3"
  },
  "console": {
    "color_scheme": "default",
    "syntax_theme": "dracula"
  },
  "preview": {
    "show_cell_borders": true
  }
}

euporie log:

euporie --version not working, prints the following

two suggestions

Thanks for very good repo. I'm from vim world and because of so much distractions, can't handle work in Juyterlab in browser.
two suggestions though:

selecting in output window.
when we get an error, we have have to select it by mouse, which is not convenient. it would be better if we could switch window and be in 'visual mode' in output window to be able to copy text and search later.
vim like syntax inside cells.
it would be better if we could use the superpowers that vim give to us, I mean something like this

[Feature request] Toggle top menu

Thanks for the great project!

Is there an option to toggle whether the top menu (File, Edit, etc.) is displayed, and can this be activated by a keyboard shortcut? Having the ability to remove the top menu at times would aid a minimalist setup greatly.

Define Custom Keybindings

Hi @joouha
Is there a way to define custom keybindings? Most of the keybindings (Ctrl+N, etc) conflict with emacs keybindings/ terminals. So for the stuff that I rarely use, I'd probably turn them off.

Right now it's not possible to load some config right? I presume I need to change https://github.com/joouha/euporie/blob/main/euporie/key_binding/bindings/micro.py

Maybe having an easy method for editing custom keybindings could be an interesting addition. I might look into this.

It would be great if Euporie has "Undo Delete Cells" feature similar to Jupyter.

Alternatively, it would be also helpful to have an option to back up the deleted cells in the tmp directory (e.g. /tmp/euporie_deleted_cell_2022-12-30T23:59:59.py) so that users can recover later.

Configuration options

here it says that "configuration options are listed below", but nothing is listed
here it talks about the configuration file, but it is not explained what are the valid configuration options.
My understanding is that they are the same as the command line options, but (1) without the -- at the start, (2) with - in the middle substituted with _ (e.g. the --color-scheme command line options becomes the color_scheme config file option), and (3) command line options that don't take parameters are boolean options in the config file.
I think we should write that.

Euporie fails to open notebook files with pandas dataframe HTML in cell output

Issue

I noticed that Euporie fails to open notebook files with pandas dataframe HTML in a cell output.

Reproducing steps:

Prepare Python 3.8 environment with pandas (e.g. 1.3.3)
Install euporie version 1.6.2.

pip install euporie==1.6.2

Create and open a new notebook.

euporie foobar.ipynb

Run a code cell which outputs a pandas dataframe HTML.

import pandas as pd

pd.DataFrame()

Save and close the notebook.
Try opening the notebook, but fails to open after several seconds without any errors.

euporie foobar.ipynb

[Workaround] After removing the output from the notebook file, it can be opened by Euporie.

jupyter nbconvert --clear-output --inplace foobar.ipynb
